  • CATALYTIC HYDROGENATION OF FLUOROOLEFINS, ALPHA- ALUMINA SUPPORTED PALLADIUM COMPOSITIONS AND THEIR USE AS HYDROGENATION CATALYSTS
    Publication number: 20230312443
    Abstract: A hydrogenation process is disclosed. The process involves reacting a fluoroolefin with H2 in a reaction zone in the presence of a palladium catalyst to produce a hydrofluoroalkane product, wherein the palladium catalyst comprises palladium supported on a carrier wherein the palladium concentration is from about 0.001 wt % to about 0.2 wt % based on the total weight of the palladium and the carrier. Also disclosed is a palladium catalyst composition consisting essentially of palladium supported on ?-Al2O3 wherein the palladium concentration is from about 0.001 wt % to about 0.2 wt % based on the total weight of the palladium and the ?-Al2O3.
